We've been looking at the Appointed Day, the Last Day in God's prophetic great Week of the plan of redemption. It dawns with the rapture and concludes with the final great white throne judgment. As we've seen, some will arise to everlasting life and others will arise to shame and everlasting contempt (Daniel 12:2).
Among those who arise to spend eternity with God are the Old Testament saints, including the prophet Daniel. "But you, go your way till the end; for you shall rest, and will arise to your inheritance at the end of the Days" (Daniel 12:13, emphasis added).
Every enemy is defeated, including Death and Hades. Satan's final sentence and incarceration is done. Eternal righteousness has come to the new heavens and the new earth. The restoration of all things is complete. It is the end of the great Week and the end of the Days.
So then what? Does a new "week" start? Or perhaps a new Day, an 8th Day? If you take the number 8 and lay it on its side, you get the symbol of eternity. That's our clue. What comes next is eternity future. It has several names in the Bible: the Day of God, the Perfect Day, and the Unknown Day and Hour.
That last one might surprise you. Jesus spoke about this unique Day when He mentioned heaven and earth passing away in Matthew 24. That is, when God makes the new heavens and the new earth. It is "unknown" because mere mortals cannot comprehend an eternal Day.
"The sun shall no longer be your light by day, nor for brightness shall the moon give light to you; but the Lord will be to you an everlasting light, and your God your glory. Your sun shall no longer go down, nor shall your moon withdraw itself; for the Lord will be your everlasting light, and the days of your mourning shall be ended" (Isaiah 60:19-20).
The Day never ends. Mind-boggling. Can we possibly imagine the glory of that Eternal Day when there is no sorrow, pain, sickness, death, injustice, war, tragedy, sin, deceit. . . ? "Oh Happy Day!" Nope, that doesn't do it justice.
If you've ever been blessed by being in the manifested presence of God on earth, then you've tasted of that glory. Now multiply that a zillion times over! No wonder we cry out, "Blessing and glory and wisdom and thanksgiving and honor and power and might be to our God forever and ever!"
